Can Keloids Become Cancerous?

Keloids Are Not Dangerous
Confirm keloid diagnosis
Treat keloids and undergo an examination to obtain the right diagnosis
Keloids are not at increasing risk of cancer. However, I have seen patients who thought they had keloids, but in fact, had a skin lesion that was in fact more dangerous.

Can Keloids Become Cancerous
One can never say never, but carcinogenic transformation in a keloid would be highly unusual. It would be described as a "case report", or medical oddball. Dr. Oppenheim's comment about misdiagnosis is very true.
No Keloids Cannot Become Cancerous
A keloid is due to an over-enthusiastic response to injury. It is benign overgrowth of fibrous tissue leaping over the boundaries of normal healing.
Occasionally, there can be a misdiagnosis. What is thought to be a keloid may in fact be a malignancy such as a dermatofibroma protuberans ( DFSP), a sclerotic basal cell carcinoma, or a malignancy developing from a scar, especially one that has been irradiated. However, a keloid itself, though sometimes growing, does not transform into a malignancy.
Can keloids become cancers
Any abnoramility in the skin can potentially become a skin cancer especially in the presence of chronic irritation. The question is what is the likelihood of that happening. In the case of keloids that likelihood is extremely low and would be more dependent on the cause of the keloid than the keloid itself.
